Itsten 200mg Capsule belongs to a group of medicines called antifungals. It works by stopping the growth of fungi and is used to treat infections of the mouth, throat, vagina, and other parts of the body including fingernails and toenails. It kills fungi by destroying the fungal cell membrane. Itsten 200mg Capsule should be taken in the dose and duration as prescribed by your doctor. It should be swallowed whole and can be taken with food. To get the most benefit, take this medicine at evenly spaced times and continue using it until your prescription is finished, even if your symptoms disappear after a few days. If you stop the treatment too early, the infection may return and if you miss doses you can increase your risk of infections that are resistant to further treatment. Tell your doctor if the infection does not get better or if it gets worse. The most common side effects of this medicine include nausea, common cold, cough, blurred vision, and a problem with menstrual periods. You could ask your doctor about ways of preventing or reducing these effects. Get emergency medical help if you have signs of an allergic reaction like severe skin rash, tingling, difficulty breathing, swelling of your face, lips, tongue, or throat. Do not take it if you are pregnant or could become pregnant unless your doctor has told you to. Talk to your doctor before taking this medicine if you have ever had heart failure, a weak immune system (including HIV/AIDS), kidney problems, or liver problems such as yellow skin (jaundice). This medicine may not be suitable for you. If your course of treatment is for more than a month, your doctor may want to check your liver by testing your blood.
